ticularly those 4on hay carriers like that shown lli Ferris Patent No. y1,759,549,granted May 20,

".1930, wherein there is a short section oi' steel [rope or cable connected at one vemi to the carrier, vand at. the other to the manila or other fiber rope.

An object of this invention is to provide a conneetion between the steel cable andthe maniia rope which is flexible so as to pass readily around' the sheavesr of the carrier and which firmly grips the fiber rope without injury thereto.

' This and other objects, as will hereinafter ap- .f pear, are accomplished by this invention which is fully described in the following speciiication and shown in the accompanying drawing, in which- Figure 1 is a side elevation oi the end of a manila rope having the rope grip oi this invention applied thereto;

Fig. 2 is an enlarged elevation of the rope grip removed;

Fig. 3 is an enlarged seetionon the line 3 3 of Fig. 1;

Fig. 4 ls a view similar to Fig. 2 showing a modified form of the rope grip;

Fig. 5 is a view similar to Fig. 4 showing the end of still another modiiled form oi anchoring device for the rope grip;

Fig. 6 is a view similar to Fig. 3 showing another form of anchor;

Fig. '7 is aview similar to Fig. 1 showing a modiiled form of grip connecting two'abutting rope ends; and

Fig. 8 is still another modiiied form of rope grip- The 'embodiment shown in Figs. 1, 2 and 3 comprises a rope grip A applied to a manila rope B, The rope grip consisting of a flexible braided tubular structure, as shown in Fig. 2, consists of strands I0 each made up oi' a number of wires twisted together to form a rope of steel, brass. or the like interwoven with similar ropes I I running in the opposite direction, These ropes having their beginning at the bottom of Fig. 2 pass up and are braided, as shown, or bent to form the loop I2, and on their return are interwoven with the opposite ends of the strands and terminate at the bottom of Fig. 2.

' One of the strands I0 is then twisted with one of the strands II at the bottom to i'orm a pig tail" I3 which preferably has an enlarged end Il, whichv in this case may be a drop oi solder. To assist in keeping the strands of the loop I2 together ythey may be soldered at Il. or they may be held by meansofabandwhichispassed around the several strands and secured thereto as by means o! solder.

In use the free end BL of the manila rope may be passed upwardly through the Atubular grip which is enlarged by pressing the ends toward 5 each other after the manila rope has been carried well up toward the loop I2, the rope grip is pulled down so as to press it firmly against the manila rope. When the lower end oi' the rope grip is reached, the pig. tails Ilmay be forced through between the strands forming the rope as shown in Fig. 1. The hold which the strands oi the rope thus have upon these pig tails is not relatively very great, but it is suiilcienttn hold these pig tails thereby "snubbing them. so that when a strong pull comes on the loop I2 the flexible grip will close in about the manila rope so as to iirmly grip the same.

To the loop I2 is secured a steel rope or cable 41, corresponding to the cable 41 of the patent, having an eye 48 connected directly to the loop or (as shown) by means of a link 49. This grip has proved to be very satisfactory in use. By carrying the fiber rope well up into the loop I2 the loop has no tendency to twist in use which is very necessary to prevent breakage of the strands forming the loop.

f In Fig. 4 the strands of wire rope I6 start at the loop I1, run diagonally to the bottom of the grip and in returning at Il* in the reverse direction are interwoven with or braided into the opposite ends so as to form a similar grip, the lends I8 of the strands overlapping the ends I1 and being secured thereto as by means of solder )Il Pieces of wire or wire rope 20' are then looped through the lower ends of this rope grip and are twisted to form pig tails which, if desired, may have solder beads 2l at the lower ends to better enable the strands of manila rope to hold these "pig tails in the same way as has been shown in Fig. 1.

In Fig. 5 is shown still another modiiled form of anchor consisting of a flexible member 22 made ot wire or wire rope with its ends secured to the lower ends of a braided wire grip which may otherwise be the same as that shown in Fig. 4.

In Fig. 6 is still another modified form of anchor consisting of a staple 23 which passes through the lower end of the braided tubular portion of a wire grip like that oi Fig. 4, and having ends 23 which are bent back to nrmly lock the lower endl of the tubular rope grip to the manila rope. v

In\ Fig. 'l is shown a modiiled form oi the grip for seciu'ing together two abutting ends o1' manila ropesCandD. Inthiscasethe gripEissimilar to the grip A except that its two ends are like the lower end of the grip A and each is provided with pig tails I3* or the like for insertion between strands of the manila ropes in the way as isshown in Fig. l. It will be understood, however, that any oi' the other forms oi' anchoring devices shown and described may be used.

While this grip is shown as applied to the end of a rope, it may be used intermediate the ends of the rope, as shown in Fig. 8. In this form the grip F has pig tails I3 extending through the tilm rope G as before, while the opposite end of the grip F terminates in a ring H of rubber or the like having a core H' of fabric, metal rope or the like about which the metal cables or ropes F forming the grip are passed at their middle, after which the ends are wound in opposite directions about a common axis and braided, the ends then being wound together in pairs to form pig tails as in Fig. 2. It will be obvious that other variations of this forni' may be made.

The ring G can then be gripped in the same way as the cable eye 48 oi Ferris Patent No.

1,759,549 referred to above, the portion G of the ber rope extending to the left beyond the grip being attached Adirectly to the hay carrier so as to pass through the hay carrier and to replace the metal cable 41. This provides a much simpler hay carrier construction than that shown in the above patent.

Any of these grips may readily be removed by unloosing the anchoring means from the rope and sliding the braided grip along the manila rope toward its end, thereby causing the grip to expand when it will readily slide oft.

Thus it will be seen that a very simple and elcient form of rope grip is provided and one which is exible and adapts itself readily to the manila rope so that the latter can be bent around the inserted strands being enlarged to prevent their withdrawal through the rope.

2. A grip for securing together two abutting ends oi ber rope comprising a loose tubular braid composed of interwoven strands of metal rope in the form of a collapsible cylinder adapted to enclose the ends of the ropes, the ends oi' the strands being secured together in pairs andA of a length sulcient to enable them to pass between V strands oi' the ber rope to anchor the ends oi' the grip thereto so that an endwise pull will cause the grip to firmly hug the rope ends.

3. In combination, a ber rope, a. grip for ber rope comprising a loose tubular braid composed of interwoven strands of metal rope for enclosing the end of the ber rope, the ends of certain of the strands being secured together in pairs and of a length sufficient to enable them to pass between strands oi the ber rope to anchor the end of the grip thereto, the opposite ends of the grip forming a loop for enclosing the end of the ber rope, the loop being short and the end of the rope extending well up into the loop so as to hold the sides of the loop apartand prevent them from twisting about each other as the pull on the rope tends to cause it to unlay.

4. A grip for ber rope comprising a loose tubular braid composed oi interwoven strands oi metal rope for enclosing the end oi a ber rope, the ends of the strands being secured together in pairs of a length suicient to enable them to be inserted between strands of the ber rope to anchor the end of the grip thereto, and a ring adapted to surround the ber rope and to slide thereover, said ring being secured to the opposite end of the strands of the rope grip.

5. In combination, a ber rope, a tubular braid composed of interwoven strands of metal rope enclosing one end of a ber rope, the inner end of the grip having pigtails passing between the strands o! the ber rope and engaging the same for anchoring the end of the grip enclosing the ber rope to the same.

6. In combination, a ber rope, a grip for ber rope comprising a loose tubular braid composed of interwoven strands of metal rope in the form o! a hollow cylinder for enclosing a portion of the ber rope, and depending portions of the grip passing between the strands of the ber rope for anchoring the end of the grip enclosing the ber rope to the same.
